AC Characteristics for Operation
NOTE
:
1. The time to Ready depends on the value of the pull-up resistor tied R/B pin.
2. To break the sequential read cycle, CE must be held high for longer time than tCEH.
3. If reset command(FFh) is written at Ready state, the device goes into Busy for maximum 5us.
